The total amount of organic matter present in any trophic level is called biomass. The physical composition of biomass is inconsistent, but generally includes carbon, water and organic volatiles. This organic matter is used for energy. This energy production process is referred to as bioenergy.

In a plant, leaf color and leaf shape are controlled by two linked genes Leaves of the wild-type plant are red. A recessive muta

Brrunno [24]

Solution :

Red is dominant over the white leaves and pointed is dominant over smooth.

Red = R , white = r

Pointed = P , smooth = p

Red, pointed x white,smooth ------ Parents

RRPP rrpp

RP rp ----------------- Gametes

RrPp -------- $F_1$

(red, pointed)

When this $F_1$ is test crossed,

RrPp x rrpp ---- $F_1$ test cross

Gametes → rp

RP ---------- RrPp - red, pointed - 36 parental type

Rp ---------- Rprp - red, smooth - 14 re- combination

rP ----------- rrPp - white pointed - 10 re- combination

rp ----------- rrpp - white, smooth - 40 - parental type

Total = 100

As this ratio is deviating from 1:1:1:1, it indicated the two genes are linked.

Linkage strength = percentage of crossing over = map distance between the genes.

Percentage crossing = recombination frequency = percentage of recombination.

Recombination frequency $=\frac{\text{total no. of recombination}}{\text{total no. of progeny}}\times 100$

$=\frac{14+10}{100} \times 100$

= 24 %

= 24 map units

Define los tipos de proteínas que conforman la membrana

tensa zangetsu [6.8K]

Membrane proteins can be classified into two broad categories—integral (intrinsic) and peripheral (extrinsic)—based on the nature of the membrane-protein interactions (see Figure 3-32). Most biomembranes contain both types of membrane proteins.

Translate:

Las proteínas de membrana se pueden clasificar en dos categorías amplias: integrales (intrínsecas) y periféricas (extrínsecas), según la naturaleza de las interacciones membrana-proteína (véase la figura 3-32). La mayoría de las biomembranas contienen ambos tipos de proteínas de membrana.

DENIUS [597]

Answer:

Cataplexy is condition in which sudden loss of muscle tone occur.

Explanation:

Cataplexy is sudden and uncontrollable muscles weakness or paralysis that comes on during the day and is often triggered by a strong emotion such as excitement or laughter. Cataplexy occur during working hours. A more severe episode may involve total body collapse. In cataplexy the voluntary muscle tone occur. This condition is mostly associated with narcolepsy which is a sleep disorder.. Symptoms of cataplexy have;

1) Dropping eyelid.

2) Jaw dropping.

3) Neck muscle weakness.
